RICHARD D. ELLIOTT, OF HERTFORD NORTH CAROLINA.

CULTIVATOR AND ATTACHMENT.

T all whom it may concern:

Be it known that I, RIcnARo'D. ELmo'r'r, a citizen of the United States,residing at Hert-ford, in the county of Perquiman's and State of NorthCarolina, have invented a new and useful Cultivator and Attachment, ofwhich the following is a specification.

This invention relates to cultivatorsand attachments and its object isto provide a simple, durable and eflicient device of this characterwhich can be readily adjusted to any desired position relative .to thecultivator bar.

Another object is to provide a 'harrow attachment utilizing a singlestem capable of being inserted into a supporting structure in lieu ofthe stem or standard of a cultivator shovel or a device of the likenature.

With these and other objects in view the invention consists in certainnovel details of construction and combinations of parts hereinafter morefully described and pointed outin the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings: Figure 1 is a side elevation of a cultivator havingthe present improvement applied thereto. Fig. 2 is a plan view of aportion of the cultivator showing cultivator and attachments connectedthereto. Fig. 3 is a perspective view of one of the ha-rrow attachments.Fi s. 4, 5, and 6 are perspective views of diherent attachments whichmay be used in connection with the cultivator.

Referring to the figures by characters of reference, 1 designatesoppositely disposed similar angular bars'each of which is provided atits terminals with eyes 2 while another eye 3 is located at the angle ofeach bar. The two bars are connected at points adjacent their ends, byupstanding -U-shaped members 4 and 5 formed preferably of metal stripshaving laterally ext-ending feet 6. Each of these feet is provided witha series of apertures 7 any one of which is designed to receive aclamping bolt 8 extending through the bar 1. It will be seen thereforethat by connecting the parts in this manner the two bars can be held atany desired distance apart. The tongue 9 of the machine is connected tothe member 4 by means of braces 10 and this tongue has a toothed segment11 thereon on which an actuatin lever 12 is fulcrumed. An arm 13 extendsfrom the lever 12 and is connected Specification of Letters Patent.

Application filed AugustG, 1909.

Patented Mar. 8, 1910. Serial No. 511.630.

I by means of the spring 11 with the upper portion of the connectingmember 4, as indicated at15. 7 A brace lficonnects' the upper portionsof the two members *1 and 5 and secured to these members 4: and 5 arethe handle bars 17.

i It is to be understood of course that the lever 12 is provided withthe usual form of pawl 18 for engaging the segment 11 to lock the leverin any position to which it may be shifted. This lever is provided so asto permit the operator to regulate the depth of cultivation while inuse.

Standards 19 are removably mounted within the front eye 2 on the bars 1and each of these standards is provided at its lower end with alaterally extending stud 20 on which a wheel 21 is journaled. Standards22 are also removably mounted within the rear eyes 2 and Within theintermediate eyes 3, these standards 22 being provided with shovels 23atthe lower ends thereof. All of the standards 19 and 22 are designed tobe locked in adjusted position within the eyes by means of set screws24.

A boss 25 is formed on each bar 1 in front of and adjacent the-rear eye2 and another boss 26 is formed on each bar in front of and adjacent themiddle eye 3. Each boss has an opening extending through the centerthereof and through the bar while the upper face of the boss is formedwith radial teeth. The teeth on the boss26 are designed to en gagecorresponding teeth formed on one end of an arm 27 said arm being heldin engagement with the boss by means of aclamping bolt 28 extendingthrough the arm and boss and through the bar. An eye 29 is formedat thefree end of the arm '27 and this eye'is designed to receive a standard30 similar to the standards 22,'there being a shovel 31 at the lower endof the standard. The rear bosses 25 are engaged by teeth formed at oneend of arms 32, bolts 33 being extended through these'arms and thebosses for the purpose of binding the arms in engagement with saidbosses. As shown in Fig. 2, each of the arms 32 is angular and isprovided at its rear end with an eye 34. This eye is designed to receivea stem or standard 35 extending upwardl from the middle portion of a bar36 plvotally connected thereto as at 41. A head 42 1s formed on thecenter of the bar and has an actuating slot 43 for the reception of aclamping bolt 44 whereby the bar can be carried by the head 36 willoperate to pultilted and secured at any desired angle to j the standard35. U bolts 37 are extended through the head 36, each of these boltsengaging a harrow tooth 38. A shovel 39 may be arranged at one end ofeach tooth while the other end thereof may be pointed, it thus beingpossible to reverse .each tooth to permit either end thereof to be usedin harrowing the round. Set screws 39 are preferably emp oyed forlocking the stems 35 within the eyes after they have been prop erlyadjusted.

In using the device herein described the arms 32 are adjusted to desiredangles relative to the bars 1 and the stems 35 of the harrow attachmentare adjusted longitudinally within the eyes 34 and rotated so as tobring theheads 36 at desired angles to each other, said heads can thenbe tllted in the manner described it so desired. The teeth verize thesoil and, by manipulating the lever 25, motion may be transmitted fromarm 13 through s ring 14 to the forward connection 4 of the rame, thusserving to tilt the entire machine. The arms 27 can of course'beadjusted. at different angles relative to the bars so as to bring theshovels 31 at desired distances apart.

If preferred, in lieu of utilizing the harrow attachment shown in Figs.1, 2, and 3 any one or more of the forms of'shovels shown in Figs. 4, 5,and 6 can be substituted therefor, the stems 40 of the said devicesbeing inserted into the eyes 2, 3 and 34 in lieu of the other stems orstandards, they being held at any desired angles by set screws. Theforms of devices shown in Figs. 4, 5, and 6 can be utilized for breakingthe soil, for cutting Weeds, and so forth.

It is to be understood of course that various changes may be made in theconstruction and arrangement of parts without departing from the spiritor sacrificing the advantages of the invention.

What is claimed is:

1. In a cultivator opposed'side bars, adjustable connectionstherebetween, supporting wheels adjustably connected to the bars,

stress arms adjustably connected to said bars, and a barrow attachmentconnected to each of said arms, each attachment including a stemadjustable in the direction of its length, a head pivotally connected tothe stem, and a plurality of teeth detachably connected to the head.

2. A cultivator including opposed side bars, adjustable connectionstherebetween, supporting wheels, armspivotally attached to the bars,means engaging the bars and arms for holding said arms against movementrelative to the bars, and tilling devices movable with the arms andsimultaneously adjustable upwardly relative to each arm.

3. A cultivator including opposed side bars, adjustable connectionstherebetween, arms pivotally connected to the side bars, means extendingthrough the arms and bars for holding said arms against movementrelative to the bars, stems extending through and detachably mountedWithin the arms, said stems being adjustable in the direction of theirlength, and tilling devices movable with the stems.

4. A cultivator including opposed side bars, adjustable connectionstherebetween, arms pivotally mounted upon the bars, cooperatmg meansupon the bars and arms for holding said arms against movement relativeto the bars, means extending through the arms and bars for binding them'together, and a harrow attachment for each arm, each attachmentincluding a stem rotatably mountedwithin one of the arms and adjust ablein the direction of the length of the stem, a head pivotally mountedupon the stem, means for securing the head againstmovement 11 on thestem, and a series of teeth detacha ly connected to the head.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signa ture in the presence of two witnesses.
